What's up hendoc. I got your pm and I hope I can help.
First of all, there are two main components when it come to high yeild. LIGHT and the amount of room you have for your roots to grow. There are other things like Co2, nutes, etc. but you can't fix everything at once and thats not to say anything looks wrong with your set up either. As a matter of fact; its beautiful and not to mention your roots. Do you use beneficial bacteria?
Anyways, if I were you, I'd go with HID lights. Use Metal halide for veg and hps for flowers. The more light, the more bud. If everything is in the 90 to 95% range as far as efficiency you can expect a gram per watt. Also, the lights initial output isn't your biggest concern, its the amount of light at the top of the canopy. The goal is to give the plants 10,000 lumens at the canopy. For instance, a 1000 hps about 4ft away from the canopy will give you 10,000 lumens. T5's really don't have the output for heavy yeild. I use them for clones only.
I also used to grow in the hydroton. Great stuff but I hated cleaning it and it was to expensive to buy every new crop. I think you can get a pretty good yeild in your system as long as you spread your plants out good. I'll use the example of the 1000 watt hps again. (It can cover a 4 x 4 area easily) so make sure you spread them out. I did a lot of research on lights a couple of years back so I can give you lumens for any light at any distance, well almost any.
Cloning is as simple as you want it to be. They got these grow cubes out there called Rapid Rooter Cubes. There made from tree bark. Forget about the rockwool. That stuff is prehistoric. When it comes to ph, you'll always be fighting with it. It doesn't work for me because I grow big and I hate being at the lab so I keep it simple. Just use regular tap water. Cut the clone just below a node keeping it about 3" and dip it in cloning gel, (your choice of gel, but I use CloneX) then stick it in the cube. Keep it under a humidity dome and don't let the cube dry out. Use a heater if its cold. Don't ph the water, don't add nutes, don't do nothing. Just keep it simple and you'll have roots in about a week. Then you transplant them to whatever medium you'd like. REAL SIMPLE!
I hope I helped and as you go along; keep in touch. I'll help with Co2, electricity, well, just about anything. Pretty soon, you'll be at 2lbs per light. I'll be posting pics of my grow soon so you can see what a real room looks like. I was at 30lbs a month but I scaled back because I couldn't get help with trimming. Now I'm at 20 lbs and I get that off 8 lights. Thats 2.5 lbs per light! Thats pretty good if you compare to anyone out there.
What kind of strain is the indica? What about the sativa? That will make a big difference in yeild too.
There's so much I'd go crazy trying to put it in this thread. Just good luck and I'll keep an eye out for you.
